3: THRESHOLD A – (THS-A) (VOLUME)
Setting range is 1-90
Factory preset at 50
Description
Threshold A (VOLUME) control in conjunction with the Threshold B
(BIAS) controls the detector’s audio signal.
THS-A increases the audible threshold for all targets (both
rising and falling pitch).
Best results can be achieved by using a selected coil and MODE to suit
either large or small targets by either:
•
Setting Threshold A low and using an appropriate Threshold B to
set the audio threshold, or
•
Setting Threshold B to neutral and use Threshold A to create
desired threshold
Note: As Threshold A is increased, the usable Threshold B range will
decrease.
Note: If using headphones then you can keep THS-A low and listen to the
pitch change as it starts to work at a lower target signal level than
volume change.
The pitch change is unaffected by any setting of THS-A.
Adjusting
Threshold A
Select Menu Option #3, then press the button to open the
Threshold A setting, then either:
•
Increase the VOLUME number with the button.
•
Decrease the VOLUME number with the button

Notes
Tip:
The more Threshold B
can be adjusted below
neutral, then better small
target detection will be
achieved, therefore a low
Threshold A is advisable
when hunting for small
targets
